I was upgrading firmware for my W580i and I had a power failure and the process got interrupted in middle.Latter when I tried to turn it ON,there was no response at all not even a white light flash.
I thought complete the firmware upgrade process may solve my problem and I tried it again but this time my phone did not respond to it too........showing a error message saying FIRMWARE CURROPT.....FLASHING FAILED



I dont even have a backup of the GDFS.
Please someone help me solve my problem and turn my phone ON.
